Geothermal Energy

Some of the sedimentary basins in India have been found to have moderately high temperatures at significant depth, where several wells may be non-flowing and/or abandoned. The Geothermal potential from such wells can be harnessed by traditional two well systems or a single well system. In order to assess the Geothermal potential, design and develop a Geothermal plant, based on the dynamic modelling, OEC has identified areas in Gandhar oil field and in Pakahjan oil field in Gujarat.

Different petro-physical parameters have been calculated with thermal conductivity as final result taking input from well logging data. Based on seismic profiles, stratigraphy from wells and contour maps, a geological structural model has been built for the selected area. Regional temperature model (3D) was created depicting an overview of steady state temperature of the reservoir.

Dynamic modeling results of Gandhar and Pakahjan oil field indicated the radius of influence to be less than 1 km around injection well, and the reservoir has the capacity to sustain a long time heat production for 30 years. 

As drilling of wells is the most significant component of a Geothermal project cost, in order to reduce the initial development cost, OEC has identified some of the non-flowing/abandoned oil that can be re-used for geothermal application in Gandhar area of Cambay Basin.  

ONGC Energy Centre in collaboration with M/s. Talboom, Belgium, is planning to set up a pilot geothermal power project in Cambay basin based on conventional two well geothermal concepts.
